Additional Details

The S-13A1D18-E800 features a highly accurate detection voltage of 1.8V. It operates with a very low current consumption, minimizing power loss in the system. The detector is available in a small SOT-23-5 package, making it suitable for high-density circuit boards. The hysteresis feature prevents oscillation near the threshold voltage, improving noise immunity. The open-drain output allows for flexible connection to various logic levels. The operating voltage typically ranges from 1.5V to 5.5V. SII Semiconductor's manufacturing process ensures high reliability and long operating life. The S-13A1 series offers different detection voltage options, so it's essential to verify that the S-13A1D18-E800 variant specifically provides a 1.8V detection voltage for your application. The detection voltage accuracy is typically +/- 1.5%. The output voltage is equal to the supply voltage when the input voltage is above the detection threshold. When the input voltage falls below the detection threshold, the output is pulled low by an external pull-up resistor. Detailed electrical characteristics, including detection voltage versus temperature and supply current, can be found in the SII Semiconductor datasheet. The operating temperature range is generally between -40°C and +85°C. Its lead-free construction also ensures compliance with environmental regulations.
